Question
can you help me with this question please?

f(x)=logbase3(4-x)


and
f(x)=-2log(2x-1)

Answer
f(x) = log(3)(4 - x)
f(x) = (log(4 - x))/(log(3))

VA = 4
x-intercept = 3
y-intercept = log(4)/log(3)
Domain is x <= 4

----------------------------------

f(x) = -2log(2x - 1)
f(x) = -2(log(2x - 1))
if this one has no base.

x-intercept = 1
y-intercept doesn't have one
VA = (1/2)
Domain = x >= (1/2)

go to http://www.calculator.com/calcs/GCalc.html

type in log(4 - x)/log(3), click enter on the keyboard, as for the next one, type in -2log(2x - 1)

for the intercepts, type in 0 for x to find the y-intercept and 0 for y to find the x-intercept
